Talking dirty

My friend, Pieter, at Toad Hill, near Mansfield in the Mulmur Hills, recently e-mailed me a fascinating, albeit lengthy, piece entitled: "The Origin & Common Usage of British Swear-words". It was very informative and somewhat titillating. I won't post it here, but it does start with this warning: "This entry discusses the etymology and application of a selection of words that, to varying degrees, can be considered vulgar and offensive. As a necessity, this entails the use of said words, and it is strongly advised that, should you find such words distressing or inappropriate, you do not read on beyond this point". Well, that stopped me dead in my tracks. Yeah, sure it did!
It went on dredging up many old and new, rude and crude words, names and phrases. Many of them referred to body parts and body functions. It was all very educational and I was familiar with one or two of the terms. I did have an ever-so-slightly queasy feeling at the end of it, but felt I should reply to Pieter's generous sharing of the information.
I sent him the following haiku, and directed him especially to an acronymical riddle in the third line. You, dear reader, are invited to solve the riddle also. And for those of you who need the benefit of academic research to solve the riddle, I direct you to http://www.bbc.co.uk/dna/h2g2/A753527 .
